FORCE-PUMP.

Specification forming part of Letters Patent No. 56,556, dated July 24, 1866.

To all whom 'it 'may concern:

Be it known that I, EDWARD B. HARRIS, of Wilmington, in the county of Will and State of Illinois, have invented a new and Improvedl Force-Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a vertical section of my invention, taken in the line 0c x, Fig. 2; Fig. 2, a horizontalsection of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate .like parts.

rI his invention relates to anew and improved double-acting forcc-pump by which it is believed water may be elevated with a very moderate expenditure of power and with a simple arrangement of parts.

A represents the well, and B the top or cover thereof, through which the two cylinders (l C ofthe pump work. The upper ends of these cylinders are connected by bails D D to a brake or lever, E, the fulcruma of which is midway between the points of attachment of the bails to the brake or lever, the fnlcrum a having its bearing in the upper end of an upright, F, attached to the top of cover B. The cylinders C G extend down nearly to the bottom of the well, and in their bottoms there are one more valves, D, opening upward.

' E E are two vertical rods, the lower ends of which are rmly secured at the bottom of the well. These rods pass centrally through the bottoms of the cylinders and have circular disks F at their upper ends, which disks are tted water-tight in the cylinders, but not interfering with the movement or working of said cylinders. These disks F each contain a valve, G, opening upward, and within each cylinder, above the disks F, there is an abutment or partition, H, containing a valve, I, opening upward.

From the above description it will be seen that as one cylinder C is forced downward the other rises, the valves D in the bottom of the descending cylinder opening to allow the water to pass into said cylinder, which, when it rises, forces the water through the valve G in the stationary disk F, said cylinder, when it again descends, causing the water to be forced through Valve D in the partition H, the water, when the cylinder is again raised, being ejected from the top of the cylinder. The same operation is going on in the other cylinder, one cylinder rising as the other descends. rIhe water is discharged from the upper ends of the cylinders C G into a trough, J, on the top or cover B, and passes off through a spout, K, from trough J.

By this arrangement the cylinders C G work in a balanced state, but little power is required to operate the pump, and a continuous stream is discharged by it.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Witnesses:
